Subject Multiple server.xml config files
Date Thu, 13 Jul 2000 11:31:16 GMT
I got sick of having to copy-and-paste my contexts into server.xml
every time I unpacked a new distribution.  So I hacked in the
following feature:

On startup, Tomcat.java loads server.xml, then loads all files named
server-*.xml in the same directory.

(If the user specifies a -config foo.xml on the command line, it looks
for foo-*.xml.)

Sample conf/server-purple.xml :

<Server>
   <ContextManager>
        <Context path="/purple" 
                 docBase="d:/dev/projects/web/sites/www.purpletech.com" 
                 debug="0" 
                 reloadable="true" > 
        </Context>
   </ContextManager>
</Server>

It's not pretty, it's not robust, but it works, sort of.  It only
works for -new- objects, like contexts; if you try to reconfigure old
objects, like Loggers, the behavior is undefined.

I'll put the patch in this email.  Is there any interest whatsoever in
checking it into the main source tree?  The only good thing is, if you
don't know about it, it won't hurt you.

 - Alex
